EJSCREEN is a new interactive mapping tool released by the Environmental Protection Agency which lets you visualize tons of location data the agency has collected on both pollution and poverty, on top of clickable, draggable and zoomable maps.

EJSCREEN, which anyone can use through the EPA's website, pulls in the agency's pollution data and intersects it with census data, so users concretely see where groups and industries are being particularly destructive to the environment, and where people are being disproportionately exposed to pollution. It overlays 12 environmental indicators, such as air particulate matter, lead paint and proximity to waterway dischargers, with six demographic indicators, including low income populations and percent minority.

The EJSCREEN maps are color coded to show different levels of pollution, with grey representing low levels of pollution and and bright red for the highest levels. On the poverty map, gray represents low levels of poverty, red high.
